16 Claims. (Cl. 167-92) The application is a continuation of application Serial No. 755,870, filed August 19, 1958, now abandoned.

This invention relates to compressed face powders and it has particular relation to cosmetic compositions adapted to be used in the form of a cake in compacts.

The main object of the present invention is to provide cosmetic compositions of the above mentioned type which can be prepared substantially without the use of water or aqueous solutions, and without emulsifying agents, and in their compressed cake form transfer readily to a wet puff and can be applied easily and conveniently, to form a flexible and resistant film on the skin.

We have found that by intimately mixing a mixture of filler or texture powders of the type described hereinafter with a mixture of components having lubricating value and with preserving or antiseptic agents, substantially in the absence of water and emulsifying agents a face powder composition can be obtained, which can be compressed in conventional manner to a face powder cake having the valuable characteristics described hereinafter.

We have found that in carrying out the present invention a combination of the ingredients described hereinafter must be used and these ingredients must be applied in the proportions described hereinafter in order to obtain a powder cake having the desired properties.

In carrying out our invention, texture materials, a wetting agent, titanium dioxide, zinc stearate, and inorganic pigments, are combined by mixing in the manner described hereinafter with lubricating ingredients, preserving and antiseptic agents and perfume and the mixture resulting in the form of powder is then compressed to cakes in conventional manner.

The following examples describe specific embodiments of and best modes for carrying out the invention to which the invention is not limited.

Example 1 A composition embodying the present invention is prepared from the following ingredients:

Alkyl dimethyl benzyl ammonium chloride- 5 0% 0.20 Methyl-para-hydroxy-benzoate 0.09 Propyl-para-hydroXy-benzoate 0.09 Perfume 0.12

ICC

In preparing a composition from the above named ingredients all of the dry powdered nonmedicated materials (talcum, sodium lauryl sulfate, titanium dioxide, zinc steal-ate, and inorganic pigments) are incorporated in a conventional ribbon mixer and continuously mixed for about an hour. The above mentioned medicating materials are thoroughly mixed and are then introduced into said mixer and continually mixed therein with the mixture of nonmedicated materials for about 2 hours. The resulting mixed batch is removed from the ribbon mixer and passed through a micro pulverizer using a number 0.013 screen. During this step the temperature of the material must not be permitted to rise more than 10 C. above room temperature. The batch is then allowed to cool to room temperature, e.g., 15-22 C., and once again passed through the micro pulverizer under the same conditions as above. The mineral oil, spermaceti, lanolin and glycerin are then mixed under heating to a liquid mixture, sprayed into the dry batch and the latter is now mixed in a ribbon mixer for about /2 hour. The batch is then removed from the ribbon mixer, passed through a comminuter and once again passed through a pulverizer using a screen, whereby the temperature of the material is not permitted to rise by more than 10 C. above room temperature, i.e., to less than 37 C. The batch is now allowed to cool to room temperature and once again passed through the micro pulverizer using a number 0.027 screen. The material is allowed to cool to room temperature and passed through a number 40 mesh screen, no heat being permitted to be generated during this final screen process. The material thus obtained is filled into cake pans which may be made of aluminum, vinyl resin coated tin plate, glass or plastic and are first sprayed on their interior surface with a thin, e.g., 30% solution in water of Clarpic and allowed to dry. The powder filled pans are put into a press and the air is squeezed out of the powder in the pans. According to conventional proce dure, in order to convert the powder into cake, e.g., a pressure of about 10 lbs. per square inch or the conventional pressure of 40-50 lbs. per square inch is then applied to the powder in the pan by means of a suitably shaped steel die which is provided with a covered rubber dam.

Further embodiments of the compositions according to the present invention are illustrated by the following examples, it being understood that the figures are percent by weight and the process used in these examples is substantially the same as described in the above Example 1.

In preparing the compositions according to the present invention, other ingredients, such as, e.g., milk, sugar, starch, marshmallow root, kaolin, magnesium oxide, magnesium carbonate, diatomaceous earth and bentonite, can be used as a substitute for an equal amount of talcum in amounts of 110% (based on the Weight of talcum) to provide proper form and consistency to the pressed cake. Such partial substitutions may be necessary when other substitutions or the additions described hereinafter are made in the formulas of the above examples, as every material has its cohesive and/ or packing compressibility, to which the formula should be adapted in the case of substitutions or additions.

To the ingredients described in the formulas of the above examples, other ingredients, such as resorcin, resorcin monoacetate, sulfur, and 'benzoic acid may be added in amounts of 1.05.0% (based on the weight of the total composition) or they may be substituted for equal weights of the salicylic acid or allantoin. Other chlorinated phenols having germicidal or bactericidalproperties may be used instead of hexochlorophene and other quaternary Ingredient Ex. 2 Ex. 3 Ex. 4 Ex. 5 Ex. 0 Ex. 7 Ex. 8 Ex. 9 Ex. 10
